l'o all whom, it may concern:

Be it known that I, FRANK ERNEsT N EL- SON, a citizen of the UnitedStates, residing at Santa Barbara, in the county of Santa State ofCalifornia, have in vented new and useful Improvements in Oil Burners,of which the following is a specifi cation.

My invention pertains to oil-burners; and it contemplates the provisionof a simple, durable, and highly-efficient oil-burner of the retort typeand one so constructed that it may be expeditiously cleared of asphaltumand other sediment at intervals with a view of maintaining itsefliciency for an indefinite period. a

The invention will befully understood from the following description andclaims, when taken in connection with the accompanying drawings, formingpart of this specification, in which Figure 1 is a view, partly inelevation and partly in section, illustrating the arrangement of mynovel oil-burner relative to the wall of the fire-box in a stove or thelike. Fig. 2 is a perspective view of the burnerre moved. Fig. 3 is adetail top plan view of the outer portion of the burner z'. 6., theportion that is adapted to be disposed outside the wall of the fire-box;and Fig. 4 is a detail longitudinal central section of the in nerportion of the burner.

Similar letters designate corresponding parts in all of the views of thedrawings, re ferring to which A is a wall of a fire-box, and B is myimproved oil-burner as a whole.

As clearly shown in the several figures of the drawings, the burner B ismade up of a retort C, open at its outer end, as indicated by a, a pipeD, leading from the retort, preferably from the upper side thereof andhaving a portion 1) disposed below the retort and provided with avapor-jet aperture 0, a head E, provided with a flange (Z, and anoutwardly-directed threaded stem 0 and having for its function tonormally close the open end (L of the retort, a yoke F and a nut G,designed to be used in connection with the yoke and the threaded stem ofthe head E to tightly secure the said head to the retort. The retort Cis rabbeted at its open end a, as indicated by], and it has an enlargedouter portion g, preferably of circularform in crosssection, and alsohas a flange h at the inner end of the portion g, U-shaped lugs i atdiametrically opposite points on the portion g, an oil-supply passage7', leading through the top of the portion g, and an aperture 7r in thebottom of said portion 9. The flange (Z of the head E is designed tooccupy the rabbet f of the retort, as shown in Fig. 1, in order to breakjoints and assure a vapor-tight joint between the retort and the head.The yoke F is provided with a central aperture Z, adapted to looselyreceive the stem 6 of the head E, and with inwardly-directed ends m,arranged to seat in the lugs 71 of theretortO, and the nut G is arrangedon the stem 6 between the cross-bar of the yoke and the head E, asshown. WVhen the ends m of the yoke are arranged in the lugs i of theretort and the head E is arranged against the end a of the retort andwith its stem e in the aperture Z of the yoke, it will be observed thatthe outward movement of the nut G on the said stem 6 will operate tomove the yoke outwardly, so as to tightly hold the ends m thereof in thelugs i and at the same time tightly press the head against the end a ofthe retort, so as to close the latter in a vapor and gas tight manner.It will also be observed that when the nut G is turned inwardly on thestem .2 the yoke F may be moved inwardly and out of engagement with thelugs 'i and that the yoke and the head E may then be quickly and easilyremoved from the retort. The head E is made removable, as stated, inorder to permit of the ready removal of a trough Hfrom the retortC. Thesaid trough H, which is designed to catch and hold asphaltum and othersediment in the oil, is arranged to receive oil from the supplypassageand is of a length almost equal to that of the retort. It is provided atits outer end with a handle a, preferably a foldable handle, as shown,to facilitate its being re moved from and replaced in the retort whilethe head E is off of the same. The head E being readily detachable fromthe retort and the trough H readily removable from the retort, itfollows that the burner may at intervals be quickly and easilydischarged of the sediment collected in the trough H with a view ofmaintaining the efficiency of the burner for an indefinite period.

In practice my novel burner is arranged, as shown in Fig. 1, relative tothe fire-box of a stove or the like-that is to say, the major portion ofthe retort is arranged in the fireboX,while the outer portion 9 of theretort is arranged at the outer side of the fire-boX said wall A.

From this it follows that the l head E, yoke F, and nut G are locatedwhere there is no danger of their being burned solidly together orotherwise deteriorated by the fire in the box; also, that ready accessmay be had to the head, the yoke, and the nut, and hence the head maybedisconnected and removed from the retort for the purpose stated and maybe placed on and connected to the retort in a gas-tight manner withgreat facility and without the employment of tools unless the nut ismade of such size to render necessary the employment of a wrench forturning the same.

In the operation of the burner the retort is initially heated by anysuitable means until the same is hot enough to convert the oil suppliedthrough the passage j'into vapor, when the said vapor is ignited at thejet-aperture c, \Vith this done the flame from the said. etaperture willheat the fire-box and will also maintain the retort at a high heat, soas to enable the latter to convert the oil into a highlyinflammablevapor throughout the operation of the burner.

The aperture it, which is formed in the retort portion g opposite thefuel-supply pipe j, is normally closed by a plug 7. and is designed toserve as an outlet for oil in the event of the burner being accidentallyflooded, This will obviously serve to reduce the danger of lire incidentto the use of the burner to a minimum, which is an importantdesideratum.

It is obvious that when desired any means other than a plug may beemployed to normally close the aperture 7; without involving departurefrom the scope of my invention.

From the location of the fuel-supply pipe j at the outer side of thefire-box wall A it follows that the said pipe is always cold and thatthe cold oil or distillate supplied by the pipe to the outer end of theretort C keeps said outer portion of the retort at a moderatetemperature. By reason of the pipe and the outer portion of the retort Cbeing at all times cool clogging of the pipe by asphaltum isefl'ectuallyprevented, and this, as

will be readily appreciated, is an important advantage.

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced in the present and preferredembodiment of my invention in order to impart a full, clear, and exactunderstanding of the same. I do not desire, however, to be understood asconfining myself to such specific construction and relative arrangementof parts, as such changes or n'iodil'ications may be made in practice asfairly fall within the scope of my invention as claimed.

Having described my invention, what I claim, and desire to secure byLetters Patent, is-

The combination of a fire-box, and an oilburner comprising a retortresting transversely in one wall of the fire-box and having atransversely-enlarged outer portion arranged to hear at its inner endagainst the outer side of said wall and also having an oilsupply passagein the top of the outer portion, a pipe communicating with the top ofthe interior of the inner portion of the retort and extending downwardlyat one side of the retort and then laterally'below the retort and havinga vapor-jet aperture in said lateral portion, a trough removablyarranged. in the retort, lugs at diametrically opposite points on theouter portion of the retort, a yoke having an aperture in its transverseportion and also having inwardly-directed ends on its arms removablyseated in the lugs of the retort, a head removably arranged against theouter end of the retort; said head having a threaded stem fixed withrespect thereto and extending loosely through the aperture in the yoke,and a nut mounted on said stem and disposed at the inner side of theyoke.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
